Crazy printer builder saying HI

Just thought I'd say Hi. I'm the guy who's insane dual CoreXY, 5 colour printer was on the Duet stand at the TCT show as featured in Clare's blog. Just to put the record straight, I'm not part of the Duet team - I was just there as a guest.

Hi Ephemeris. As you can gather, I have a masochistic streak which is needed for multi colour/multi material printing
It's not an E3D hot end but I do use 5 Titan extruders so I hope that qualifies me for membership of this forum.

I have no idea where you'd get PETG in Cyan, Magenta and Yellow. TBH, until someone designs a true mixing hot end, it's pointless. What comes out of a Diamond nozzle is akin to stripey toothpaste, not properly mixed at all. The colour is biased towards the nearest input so a printed object will have a different colour depending on what side you view it from. IMO You might as well use Blue, Red rather than scratch about trying to find Cyan, Magenta.
